Forum: etree Subject: bit torrent issue

I saw the announcement on Torrent Freak that the Archive was using BT for all downloads, in addition to the traditional web downloads. I thought this was great and wanted to get a couple new shows and help seed to others.

After getting the torrent file for Grateful Dead April 3, 1987 (Recording Info: Sennheiser ME80 -> Master Cassette -> Dat(44.1k) -> ZA2 -> SHN) I uploaded it to my seed box like all my torrents and some weirdness started to happen. I would successfully connect to both trackers (http://bt1.archive.org:6969 and http://bt2.archive.org:6969) I wouldn't see any seeds but thats cool.

After letting it run all night, I only downloaded about 45 megs of the 1.3 gig file set. Yet I was constantly download at between 1.8 and 2.8 meg/sec to my seed box. It appears I am downloading something but it is failing. I use Transmission on my seed box and can not actually see any users, the availability for the torrent is only 4.36% (what I probably have right now).

Wondering if anyone else is having problems with GD or even just Live Music torrents. My seed box works fine, getting and seeding torrents without issue on my side. I have checked the states page (http://bt1.archive.org/hotlist.php) and can see that people are indeed getting/seeding/hosting torrents.

The usual cause for partial download like this is that the files referenced in the Torrent changed out from under you, and Transmission kept trying to get a changed file, which would fail hash checks and retry... indefinitely.

Can you post the item name? I can take a look and see if the Torrent was remade in a way that would have caused this -- you can also try grabbing the Torrent again and retrying it. If you see a different date/size for the Torrent linked right now, that would confirm the problem.

I put a patch in recently that strikes out the Torrent while the item is being worked on, in case it changes, to try to prevent this, but it can still happen.

Thanks for getting back to me.

I did download the torrent from the Grateful Dead show again but same results. I even downloaded a NRPS show that according to the bit torrent stats had 9 seeds at the time, same results.

I will try deleting all the data and grabbing the GD show again one last time. If this doesn't work I will just grab it via HTTP download.

Here are the files that I grabbed:
gd87-04-03.sennme80.clark-miller.24898.sbeok.shnf_archive.torrent
nrps1973-03-18.fm.weiner.21538.sbeok.shnf_archive.torrent

Thanks again and I look forward to using Archive.org bittorrent in the future.

Hmm, not sure what's going on!

For gd87-04-03.sennme80.clark-miller.24898.sbeok.shnf, I just grabbed the Torrent from the item (there's only ever been one made, so it's not an out-of-date issue...), and successfully d/led with both uTorrent and Transmission, got 100% of it.

I have slightly out-of-date versions of both, Transmission is on 2.51 MacOSX, forget for uTorrent.

We've noticed that Transmission can take a looong time to start up -- I just watched mine take maybe 90 secs plus to get going, maybe even 3 minutes, even when I kicked it to update trackers. But once it got going it was fast, faster than uTorrent I'd say.

I find uTorrent starts up much faster, I suspect it's something about exhausting DHT before trying webseeding or something.

Sorry it's giving you trouble. :/ We'd be interested to hear if you get around the problem what solved it, so we can add that to the FAQ. :/
